Winter Ops

ByAndrew Robinson August 10, 2015August 19, 2015

It’s summertime and the weather is hot! Over this dry, sunny season, winter flying is probably the last thing on your mind. However, now is the perfect time to start getting things in place for winter and that includes having a plan for taking care of your airplane.

Why are preparations for winter ops needed in the first place? Cold weather, especially during the engine start and warm up period, can be very damaging to your engine if precautions aren’t taken to ensure that safe temperatures exist inside the engine before you turn the key. I always thought that the biggest problem associated with cold weather was engine oil. The logic is since cold oil is thicker and less viscous as the temperature drops, it is not able to circulate quickly throughout the engine to provide proper lubrication upon starting.

While cold oil may be a factor, the introduction of multi­viscocity oils has greatly reduced that issue. The real problem is created by the different ways that various parts of the engine respond to heat. Because aluminum expands more quickly when heated than steel does, the pistons (made of aluminum) expand more quickly than the cylinders (made of steel). This can lead to scuffing on the sides of the cylinder barrel. In the same way, differential heating can reduce clearances which are designed to provide cooling oil to bearings and other vital engine parts, thereby causing damage which greatly reduces the life of the engine.

So how cold is TOO cold? Unfortunately, that is a difficult question to answer. Because there is so much variation between engines, airplanes, and environments, there really isn’t any one specific answer. An older, more worn out engine may actually be less susceptible to cold weather damage than a newer, tighter engine because its internal clearances are probably not as tight as they were a few thousand hours ago. I have heard of some people who preheat their airplanes anytime the temperature falls below about 40 degrees. For us northerners, this seems excessive. On our E33A Bonanza which has a Continental IO­520, we generally preheat the airplane when it is cold soaked in temperatures below freezing (32° F).

Here are a few of the best ways to get your machine ready for a cold weather flight:

• Heated Hangar:­ Nothing beats a heated hangar for warming up an airplane. The warm air is evenly distributed around the engine and in the cockpit (your avionics and gyros will thank you!). The airplane will need to be in the hangar for a while in order to warm up the guts of the engine. Often, the easiest way is to have the airplane pulled in the evening before the planned departure and left overnight. Many FBOs will hangar airplanes overnight for a small fee and it is well worth the price. We almost always have our charter airplanes put into hangars overnight when on a winter trip to ensure that we don’t have any trouble when we depart the next day. This practice has the added benefit of keeping the airframe clear of any ice and snow that may accumulate before you are scheduled to leave.
• Electric Engine Heaters­: Multi­point electronic heaters use heating pads that are placed around the engine in order to heat up the various components such as cylinders, the oil pan and crankcase. Most of these systems are designed to be activated by being plugged into a wall outlet with an extension cord. Preheating for a winter flight is as simple as going to the airport the night before and plugging it in. Two well ­known manufacturers of multi­point engine heaters are Reiff and Tanis. These systems are relatively inexpensive and can be a life saver if you regularly travel in colder climates. If an engine heater is the right choice for you, it is recommended to avoid less ­expensive models that heat only the oil pan.

• Covers and Blankets­: If it is especially cold or you have to preheat outside, having something to insulate the cowling and keep the wind out can be very useful. Regular blankets will work long as you can secure them in place. If you have an ongoing need for additional insulation, there are companies that make custom blankets and propeller covers to fit your airplane. If you are landing and then taking off again relatively quickly, using a few blankets and cowl plugs will work nicely to keep the engine warm while it is sitting outside. In a pinch, placing a couple of powered light bulbs in the cowling overnight with insulation on top can result in sufficient temperatures for starting the engine.

• Forced Air:­ This method is used widely by FBO’s and flight schools. Hot air is produced in a portable heater and is then pumped into the engine compartment via the openings at the front or bottom of the cowling. This method has the benefit of not requiring any additional equipment to be installed on the aircraft beforehand and can be very effective provided there is adequate time for the engine to heat completely before removal.

• Winter Baffles:­ When the air temperature starts to drop into the teens and lower, you may find it difficult to keep your engine temperatures warm enough in cruise flight. The problem is that the air entering the cowling inlets is so cold that it overcools the engine. The solution is to install additional baffling in the engine inlets to reduce the amount of airflow into the cowling. These additional baffles are usually just sheets of aluminum that are cut to the correct size and are bolted in and removed quickly and easily as needed. Some pilots swear by them while others complain that they can cause uneven cooling. If you have questions about winter baffling, I’d suggest talking to your mechanic about your specific airplane.

Winter flying can be extremely rewarding. After their hands thaw from pre­flight, a pilot is often rewarded with smooth air, improved performance and outstanding views. Just don’t forget to prepare the airplane for the cold. The preparation is often as simple as plugging in an extension cord or making a phone call to the FBO. So whether you live in the north or the south, take good care of your engine so that it can keep taking good care of you.

Maintaining TKS Panels

ByHank Gibson June 14, 2016June 14, 2016

When cleaning airplanes, the majority of people don’t know how to properly maintain their TKS panels.  TKS panels provide wing leading edge, horizontal stabilizer leading edge, and, in the case of FIKI airplanes, vertical stabilizer leading edge de-icing protection.  For those not familiar with them, they are metal strips that have thousands of holes drilled into them where the TKS fluid seeps out. They have become quite prevalent on Cirrus aircraft, the Cessna TTx, and Mooney aircraft manufactured in the last decade or so.  The system is also known as a weeping wing system.

Being on the leading edges, these panels pick up bugs very easily.  For the uninitiated, it would make sense to just use normal airplane cleaner to spray the panels and scrub the bugs.  Don’t!

Using anything that contains Methyl Ethyl Ketone (MEK) as that can harm the TKS bladders behind the panels.  Any aircraft cleaner containing wax could cause the pores to clog, preventing the TKS fluid from properly seeping onto the wing.

What’s the best thing to do?  Soap and water with a soft cloth is a good start (again, make sure it doesn’t have wax in it.  Dish soap would be suitable).  No hose available?  Just simply turn the TKS system on, let it run till you start to see fluid drip off the wings onto the ground, and use the fluid to clean the panels.

A soft cloth would work fine, but, if the panels are really buggy, take a green scouring pad to do some scrubbing.  Just make sure the scrubbing motion is up and down with the grain, not side to side.  You can find the green scouring sponges on the dishwashing aisle in the grocery store.  Just leave one in the hangar for when you need it.

The Importance of Slowing Down

ByHank Gibson June 4, 2018June 4, 2018

Technology has made our job as pilots simpler, streamlined, and safer.  With all the new GPS & autopilot technology that seems to come out every month, flying an airplane is getting easier every day (and when I say flying, I mean programming!).  I can’t tell you the last time I actually used a VOR for navigation, other than a practice approach.  The AIM even has guidance in it now allowing pilots to use the GPS overlay on a VOR or LOC approach instead of switching to the actual NavAid on the course needle (you have to WAAS in order to legally do this).

I hear the argument already.  I am young (31) and used to all the different touchscreens because I have grown up with them.  Tech is nothing new to me.  It’s not that easy for everyone, I do understand.  There is also the argument that all the tech causes pilots to not know how to fly the airplane, which is also valid. This is why I put an emphasis on hand flying in any kind of training I do.

For the sake of argument in this article, yes, I am young and I adapt to technology pretty easily.  I’m not afraid to press buttons to figure out what they do, but I usually do it while sitting on the ground with a GPU hooked up (or I go look in the manual).  And yes, all the autopilot ability has caused a decrease in base pilot skills.  I actually encourage every customer I have to go get a tailwheel rating so that they can actually learn how to fly better.  You don’t use a rudder much in a Cirrus compared to a Super Cub or a Citabria.

What I want to focus on for a few minutes is how to alleviate the frustration that comes with getting so wrapped up in the technology when it doesn’t do something that you want it to, or the wrong button gets pressed, then you end up somewhere you had no intention of being.

The biggest thing a pilot can do when it comes to technology is NEVER to get in a hurry.  Good training is first and foremost, but, after that when flying without an instructor or even in recurrent training, SLOW DOWN and think through what you are doing and what you want the system to do.  This will alleviate a ton of frustration.

It can be very easy in hot, turbulent weather to get tuned in to the GPS programming, trying to do five or six different things in the span of five or six seconds, before looking up and realizing that plane is 500 feet off altitude (without an autopilot) or you blew through the course you were supposed to be intercepting (with an autopilot).

What I teach is to slow down, whether or not you have an autopilot, and do one thing at a time.  Once that item is done, look up at the instruments or the horizon, check on things, make sure the airplane is still flying properly, then do the next thing.  Don’t try and do a bunch of things all at once or in a hurry.  It will usually get you off course and off altitude, plus it distracts the pilot from his main job:  Flying the airplane.

So, next time you want to do something on your GPS, pause, take a breath, think through what you want to do, then do one item at a time.  The outcome will be less frustrating and you’ll keep flying where you want to go.
